To all whom-it may concern:

Be it known that I, J OHN M. BROWNING, a

V citizen of the United States, residing in Ogden. in the county oflVeber and State of and the closing and locking of the breech areautomatically effected through or by the energy of the recoilof thebreech-bolt or that part which at the. time of firing the shot closesthe breech of the barrel, and the invention more especially relates tofirearms of this description in'av-hich, in firing, the barrel andthebreech-bolt are interlocked and rec-cit some distance together, andduring this rearwardmovement the barrelhas an= other movement im artedto'it, whereby it'is unlocked from the reech-bolt, andiafter its releasethe movements of the barrel are ar-- rested, while the breech-boltcontinues to recoil until the breech is fully opened, and in whichduring the opening movement of the breechg-bolt energy is stored in aspring, the reaction of which is utilized to effect the return orclosing movementmf the breech-bolt.

l t essentialfor the proper operation-of firearms of this class that thebreechrbolt and the parts connected and moving with it should be made asheavy as practicable, so that it may store-a i'naximum amount of en-'ergy'in the short time during which on fir ing the rearward pressure ofthe powdergases in .the barrel acts upon the breech bolt and initiatesits recoil, 'and] so that the breech-bolt may continue to recoil underits momentum alone to complete the opening of the breech and thecompression of the reaction-spring after the gas pressure has ceasedbeause 'relievedby the exit of the bullet-from thebarrel. On account ofthe limited total weight practical for a smallarm, and especially for apistol, it is necessary in order to'be able to give a maximum weight tothe breeclrbolt, that the other parts of the arm, theframeand' thebarrel, be con-' structed as'light as possible. This is especiallyimportant regarding the barrel of this class of arms, for the additionalreason that at the-commencing ofthe'recoil the light barrel may readilyyield to and move rear ward with the breech-bolt while 'it' remainsinterlocked therewith, and in order that when unlocked from thebreech-bolt, the movements of the barrel may be arrested, withoutcausingby this sudden stopping injury to either the barrel or the frameof the arm.

in order to be specially adapted for the military service, shall be "notonly practical, efli- I cient and'perfectly safe in use, but strong andcapable of withstanding the exposure and rough usage of service in thefield and adaptedto fire cartridges having bullets of large caliber andweight and powerful charges of powder; it shall also be very simple inconstruction so as to be reliable under all conditions of service andnot liable to get out of order, inexpensive of manufacture,

readily dismounted and cleaned without requiring the use of any tools.

Another object of the invention is to produce a firearm of this .classin which to insure the absolute safety of the user the breech-slide,comprising the breech-bolt and the forward extension of the samecovering -onc strong integral whole without a division the top of theframe from the front, to be so held and guided in its reciprocationthereon thatit can be removed from theframe as one whole only and illtile forward direction alone, by which the possibility of'any part ofthe arm being thrown rearward shall be positively guarded'against.

thebarrel, and the movable abutment inclos-' mg the reaction-springshall be combined 1n The main object of the present invention is toproduce a firearm of this class which,

.80 with a, minimum number of parts, and

or joint therein and shall be mounted upon 5 Another object of theinvention is t0 1)1'0 duce a firearm of this class in which the" barrelshall first be seated in the forward partof the breech-slide, shall thenbemounted with the breech-slide upon the franie' from ,the front, andfinally thebarrel shall.

be securely connected with andmovablynt tached to the frame in such amanner that the barrel may be at will and readily detached anddisconnected from the frame, so

the breech-slide in only. 7

that it can be removed from the frame with r the forward directionAnother object of the invention is to pro- 'vide in a firearm'of thisclass a simple but strong and reliable means of attachmentand connectionbetween the barrel and the frame of the arm, which shall leave thebarrel free to recoil a limitedfdistance interlocked with thebreech-bolt and which shall during Y moved forward by the breech-boltand iin this rearward movement guide the barrel. and impart to it at thesame time another movement by which it will be unlocked from the'breechbolt, and which shall at the last of the return or forwardmovement ofthe breech-boltguide the barrel'xwhile it is part to it another movementby which the bah-e1 and the breech-bolt will be" interlocked when theyarrive at the forward fir ing position; this means of attachment andconnection shall at. the same time be the means which shall positivelylimit the rear-' ward movement of the barrelv with the breech-bolt-,arrest the movements of the barrel as soon as the same becomes unlockedfrom the breech-bolt, and which shall be; adapted in location, form andstrength to transmit to the frame the stress due to the sudden arrest ofthe movements of the barrel without injury resulting therefrom to eitherthebarrel or the frame or to' the 4 means of attachment between thesame; such means shall further positively limit and arrest the forwardor return movement of the barrel and of the breech-slide when the samarrive at the firing positi0n.-

Another object -of the invention is to produce a firearm of this classin which, to insure absolutely against the dangerous accidental firingsometimes liable to occur if the hlgge" r is ulled after the ma azinehasbeen withdrawd in the belief thah all cartridges havebeen removedfrom the arm with the magazine, whereas the loaded cartridge last fed tothe barrel still remains in the cham I her, the'magazine-catch shall notonly lock the magazine in its seat or at will release the magazine, butthe catch shall also automatically lock the trigger against operationwhenever there 1s no magazine in the seat,

.of sim 1e and will be more particularly referred to here- V inafterl a580,924, granted to me April 20th, 1897; but C it will be understoodthat I do not intend- The embodiment of my improvements represented inthe accompanying drawings is 'a magazine-pistol, such as is shown-anddescribed in the United States Patent No.

All the parts thus far referred to may be and are here shown as of thesame construction and mode of operation as fully set forth, 1n:the.sa1dPatent No. 580,924,- and' forming no part of the present inventionrequire no further, description or ,explanation; herein, except so faras certain features will be referred to hereinafter. I

The-barrel b is attached at its breech only to the" top of the frame,for this purpose the barrel havi-ng'near its rear end where it is-'large *,st and strongest a depending lug b p'roiecting downward into acentral recess a? of corresponding width in the top of the -frame,whereby the breech end of the barrel, when m ltsplaoe, is guided and itsaxis is always kept within the vertical plane through the axis of theframe. In the 131% f b is a-vcrtical central slot in which the li (Z, isseated and ,by apivot-pin attached-to the barrel. The lower part'of thelinkd is larger than the upper, andja second pivotpin 2", considerablylarger than the upper one, is fitted transversely through-the frame andthrough the link, and serves to 'movably attach the barrel b to theframe a. This attachment permits the barrel to swingon the link d, andto vmove longitudinally and at thetisame'time vertically a' limiteddistance,

the limit of this double movement in the rearward direction is thecontact of the rear face of the lug b with the rear end of the '35"recess inthe frame, and in the forward direction the"m0vement is limitedby the Y lower end of thejlug b ooming into contact with the lower.link-pin i at each side ofthe link. For. this purpose, while the lowerand forward face of the lug ,b is parti-circula-r inform, concentricwith the upper pivotpin whichholds the link to the barrel, and 019 sucharadiusthat' this part of the lug cl ars and freely moves over thelowerpivotpfin i-which -holds the link, to the. frame, t.

e rear -face of'the lug b is straight,: ex-

tending ertically down belowthe center of the lower pivot-pin z, andbetween 'the'rear face and the lower edge of-the lug this extensionforms a projection at the bottom of the lug which, coming in contactwith the lower pivot-pinfi-at the last of the forward movement oftlie'barrel, limits this movement. .The forward sideof this projection isrounded to correspond with and fit upon the pivot-pint Heretofore 1n thearms of this class in ,smallen tube, which depending downwardbreech-slide when it is mounted upofn the it was necessary to firstmount the barrel upon the frame'and attach it thereto, then to mount thebreech-slide from the rear upon the frame and slide it forward over thebarrel, and finallyto securely lock the breechslide to the frame andvconnect it with-the reacti'on-sprin therein by means of thecoinbined'slide-loc or.key,and abutment for the reaction-spring: Forease in assembling and, dismount-mg itwas necessary that this slide-lockcould be'readily put in place or' removed. lViththis arrangement andwith the breech-slide removable rearward from the frame, in case theslide-lock had not been put in place or hadnot been properly st cured,it became possible that, on firing the arm, the breech-slide mightbethrown rearward from the frame. By my improved construction thebreech-slide can be mounted upon the frame from the front only and canbe removed in'that direction-alone, and it can not under any conditionsbe thrown from the frame to the rear. V, I

The rear part of the breech-slide forms the breech-bolt 0 and forward ofthis the breech-slide extends in form' of a tube from which a part hasbeen removed opening it at the bottom. At 'the forward end the breechslide is closed at the bottom by a second from it and extending: somedistance to the rear,'with its axis parallel to that of'thobreech-slide, forms the. strong integral front, J abutment c theinteriorof which is the seat for the forw'ard portion of the reactionspring.-From the abutment 0 rearward,

throughout the remaining length ofthe breech-slide, its sides projectdownward overlapping the sides of the frame, and are provided withinternal longitudinal grooves and ribs which interlock withcorresponding ribs and grooves near the top in the sides. of

'the frame, and serve to secure the br eec l 1-. slide vertically uponthe frameandguide 1t in its movements thereon; g I

At the front ,the frame has asem -tubular extension a 'the axis of whlchcoincides with the axis of the depending abutment o of the frame,-andthe internal diameter of the' extension a corresponds-with the externaldiameter of the abutment 0 so that the abutment will enter into theextension and slide therein when the breech-slide moves. At

the rearend of the bore of the extension a the front of the top'of theframe forms a strong vertical shoulder a, at each side of themecess-a(see Figs. 12, 13 and 14) this shoulder stands in the path of thedepending abutment 0 and positively limits the, rearward" movement ofthe same. As the abutment is integral and strongly connected w th thebreech-slide, and projects into the plane of the' frame, thebreech-slide. can be mounted upon and removed from the frame the frontof the abutment-and inclosesthe forward endof the reaction-spring e. Therear end of the reaction-spring fits upon a guide-tube g'and bearsagainst a OOH-d upon n rear of the flange ase thesame, and the rear endof the guide-tube g fits into the recess a in the front of the top ofthe frame against the shoulder a of which the collar of the guide-tube'gbears.

The bore of the abutment a is open at the top, being connectedthroughout its length with the bore of the breech-slide by a verticalpassage, (see Figs. 4, 9 and 10). In the forward end of the breech-slidethe bushing 71. is 'seated,'a projecting flange k of. which restsagainst the front of the breech-slideand extends downward to theabutment I where a segmental recess k in the flange fits over andreceives the reduced end of the lug f projecting from the abutment 0ental lug It? projects from the lower su ace of the. bushing h when thebushing is fully entered and is into the pass slide to the autment, thena segmental h, at the right side of and'at an angle to the verticalplane through the axis of the bushing see Figs. 2,15, 16 and 17). Onentering a bushing in to the breech-slide the bushing is turned on itsaxis until the lug k is centrally under the bushing and enters leadingfrom the breechoove a cut in'the interior surface of the reech-slide onthe right side at the proper.

distance rearward and connecting at the right side'with the passage,receives the lug turned until the recessh? in the flange coincides withtliebo're of the abutment 0. By

this arrangement the lug It looks the bush-- ing in the breech-slide,the reduced end 'of the plug fstanding in the recess h in the flangeprevents the bushing from being "turned, and theshoulder on the plug fformed by the reduced front end of the same, is pressed 'by -thereaction-spring e gainst the flange h, and thereby transmits the.tension of the compressedreactionsprin e in forward direction to thebushing.

han through it to the breech-slide 0. The flange h of the bushing Itthus forms the front abutment for the reaction-spring, and

I Lhe bushing 1;. forms the connection between the reaetion-spring'andthe lzcJch-slide.

At the forward end the-lbushing'h fits closely upon theforward portionof the barrel b, but in'rear the bore of the bushing is enlarged so thatwhile the bushing holds the muzzle of the barrel securely in position,it

allows the rear end of the barrel to move vertically a limited distance,the barrel turn-.

, mounted upo "ing during this m'o'vement upon its forward end as upon afulcrum.

Before the barrel or the breech-slide are n the frame, the barrel 6 withthe link d attached thereto in the lug b, is

placed from the front in the breech-slide,

the depending lug and link entering and passing through the open passagebetween the breech-slide and the abutment c, then the plug is placedupon the forward end of the reaction-spring e, and fitting firmly uponthe same, the spring and the plug are from the front entered into theabutment 0 and the guide-tube g is placed in the rear end of thereaction-spring, then the plug f is pressed back into the abutment andthe bushing h is placed upon thebarrel and in the breech-slide andlocked in the same as hereinbefore described. a

The breech-slide, with the barrel and the reaction-spring contained.therein', is then mounted from the front upon the frame, the lub b andlink (I entering the recess a, the end of the guidetube g finding its.seat in the recess, and the link (1 moving rearward with the barreluntil thehole in the link for the lower pivot-pin coincides with thecorresponding -hole. in the frame, when the pivot-pin z' is inserted andpushed into its -.place, thereby securing the barrel to the frameandlimit' barrel and 'of the breech-slide u on the frame in bothdirections. For easier han-.-

dling the pivot-pin i is provided with a han- 'dle j which pro ectsat;1'-i ht angle from the end of the p1n,.and exten rearwardrestsagainst the left sideof the frame a when thepin is in its plaee, (seeFigs. 1, 3,: 21,

22 and 23.). v

within the thumb-piece j a small iston 10 and spiral spring is aresecured, see

21,22 and 23), while'a round 'stud 'lc projects from the frame at therear. of the handle, 1 'the protruding 'end of the spzinggvressed pistonk bears g n tthe stud yield- '1 moved upward and downward by the thumb;of the hand grasping'the grip, .the T6311; end;

9 the movements'of the ngly holds the handle 7' in either the rai d... 7

or lowered position to, which it may be moved at -W1ll by ressure on thethumb piece. Onthe outsi e of the frame above the thumb piece the handle5 carries an upward projection Z, and the breech-slide'has a 001:

responding recess m) 'in-iits lower edge, both projection and recessbeing square at f the rear and inclining at the front.

The-inn er end of the lug does not inter- 1 ferewith the passage'of thecartridges from the magazine to the chamber in the barrel,

but when the last cartridge has been fed from the magazine, the lug 7'stands in the path of the spring-follower of the magazine,

7' and the handle 7' and cause the projection Z to enter the recess mthe breech-slide, thereby locking the same in the open rear position.and serving as an indicator to show that the empty magazine must bereplaced by a charged one before the firing can be continued. Afterplacing the magazine-in the ip. the breech-slide is released bydepressing the handle 7'.

A slide-stopacuated by the magazine-follower to arrest the breech-slidein the open position when the magazine is empty,'has beenheretoforedescribed and shown in the United States Patent- No. 708794, granted tome September 9, 1902, but the construction of the slide-stop as anintegral part of the handle of the pivot-pin securing "the barrel andthe breech slide upon the frame, as herein shown and described, is anovel improvement which reduces the number of parts and simplifies thedismounting and assembling of the arm;

Upon the inner end the lug j of the handle carries a slight upwardprojection Z which stands inside of the lower edge of the breech-slide:and, with the breech-slide upon the frame the inner edge of the samelocks the handle 9' laterally imposition on the frame and thus locks thepivot-pin 2' against being accidentally displaced or removed, to

insure this locking even while the recess m in the edge of thebreech-slide stands above the upward projection Z on the thumb-piece,the projection l and the recess m do not extendinward entirelythroughthe edge of the breech-slide, but an uncut portion of the edge remainsforming a partition between the recess m and the interior of thebreechslide, and preventing the projection Z on the lug 7' from passingoutward through the Some distance in rear, of the recess m-va secondrecess n is cut in' the edge of the breech-slide, less high and shorterthan the forward recess m, but-cut, entirely through the edge Thelocation of this recess n is such that-in the regular 0 eration of thebreech-slide the movement 0 "the same is not arrested; when the recess nisuabove the thumb-piece j, but the-recess is carried be- 1 yond thesame in either direction, so that the projection l is not likely toenter this recess, and both ends of'the recess n are in-- clining, sothat, when the breech-slide moves "the projection I will be forceddownward out of, the wa even in the case it should havepartlyen eredinto the recess.

F01 at will removing the pivot-pin i the breeclrslide is moved rearwarduutilthe re- 'cess )2. stands above the pro ection .1, then pressure isapplied against the end of the pivot-pint protruding from the right sidethe frame, and the pin 71 and handle j will yield, the lug j with theprojection 1 upon it will pass outward'through the openmaybe removedfrom the frame in the forward direction. For replacing the pivot-pin i,the breech-slide with the spring and the barrel, is moved to the,position in which the recess .-n coincides with the opening in theframe, when the pin 91 may be inserted. the lug 7' entering through therecess n and the opening in the frame.

With the breech closed slide and barrel in the forward-position, Fig. 1,thevlink standsupright,.the end of the lug b bears against the pivot-pin11, and the rear end of the barrel is raised to its highest position inwhich the enlarged rear portion. of the barrel and two ribs of similardiameter projecting forward of the same from the barrel, occupycorresponding recess'es the top .of'the breech-slide and interlockthe'barrel and the breech-slide in firing position, while the muzzle ofthe barrel remains securelysupported in the bushing h. In thisclosedlfiringposition the barrel is therefore situated not parallel with"the top of the frame and breech-slide, but the axis of the closedbarrel inclines forslide and of the barrel delays the rearward movementof these parts until after the bullet has passed from the muzzle of thebarrel, I

the inclined position of the barrel does not mg in the frame and therecess 01, until the and the breechaffect the accuracy of the arm: Inconsev quence of the depressed position of the muzzle of the barrel atfiring, the front sight upon thebreech-slide may be much lower than itwould have to be if the muzzle were raised and the. barrel wereparallelto the breech-slide. The low front sight is a de- .cided advantage in amilitary pistol, be-

cause it facilitates thedrawin of the arm from its holster; whereas abig! front sight forms a projection very liable to catch and tointerfere with the ready drawing of the pistol. On firing, thebreech-slide recolls and carries the barrel rearward'until the rear end.of the same, swinging rearward and downward on theelink and pivot-pins,becomes unlocked from the-breech-slide and its-movements are arrested inits lowest rearward position by'the' lug b striking the and trade}thr'oughthe plate-for receiving 4 of the recess a in the frame,whil ethebreechslide continues its rearward movement, Fig. 4, during which thebushing k slides upon the forwardportion of the barrel."

The hammer pivot-pin g fitted fromthe-right side in the frame, :carries onits right end a thin integralplate 4 which rests against. side-of the frame and extends for- 4 theright ward and downward to cover the end of-the sear pivot-pin r whilethe re ar end'of the t grip-lever pivot-pin w?" gr o e-in the same theplateextends to and. enters the distance to a form the 'neces straighttopzof the plate"g" 'is parallel to and lies below the edge ef'thebr hslid I which the plate is preventedfrom turning.

When the breech-slide has been removed from the'frame, the three pivotpinsmay be readily withdrawn, for this purpose the plate g is turnedwithdrawing its rear end he groove in the grip-lever pivot-pin,uncovering the sear pivot-pin and raising the forward end of the platebeyondthe top of the-frame. This allows the plate with the pivot-pin tobe withdraw from the frame, thereby liberating the hammer q for removal.The strut g dependingfrom the hammer may then -'be-utilized to push outthe two remaining pivotins and also the pin holding the butt-piece 1nthe grip. The removable cartridge-holder or magazine. a2,'of usual formand construction, is

' locked in the grip by the magazine-catch y,

'fitted transversely through the rip in rear of the trigger, its reducedan checkered end projecting from the left side of the rip convenient foroperation by the thumb of the hand holding the grip. The cylindricalbody of the catch 3/ intersects thefrontend 0f the magazine-seat in thegrip, and a'section of the catch has been removed to correspond with andto clear the magazine seat .whenthe catch y is pressed inward from theleft toward the right side of the grip; with the catch thus pressedin,-'a magazine may be freely entered into or withdrawn from the seat inthe grip. See Figs. 4, 5, 6, 7, 7* and 7 At the right end the catch yvcarries "a projecting-lug 3 which fits into a correspending openingthrough the ri ht side of the grip and prevents the catch rom turninWithin the catch 3/ a spiral spring 3 add a piston 3 are seated, enteredfrom-the right side, the left end of the spring bearing against thebottom of the seat in the catch, 7 the right end resting againstashoulder on the piston, while a radially projecting stud f onthe pistony? extends outward through a slot in the catch 3 into an annular recessin the wall of the grip surroundin the right end of the catch. The study o the piston thus locks the same and the catch y in the grip and the.tension of the spring yis exerted to :vieldingly press the catch towardthe left side; where the reduced end of the catch projects from thegrip. Qn its inner face the lug 3 of thecatch carries a horizontallocking-rib' 3 which normally projects .into the magazine-seat, and themagazine a:

is provided on the right side near its front magazine'in the seat. 1

with a corresponding recess .2 into, which the'rib y' -enterswhen themagazine is in its place 'in the grip, the rib thereby locking the Bvpressing against the projecting left end of the catch, the same ismoved'inward so as to withdraw the locking rib out. of the magazinewhich isthereby released and free for removal from the grip; oninserting a magazine from below into the grip thpltop of the magazineencounters a beveled under-' side of the locking-rib 3 (see Figs. 7,and7",)
